XMIT defines lightweight logical sessions. A session is used to carry application messages. XMIT is responsible for using the selected communications mechanism to deliver messages orderly from one application to one or more other applications in the context of a session.

XMIT is designed to meet the requirements of automated trading in the financial markets. These include the use of open protocols, simple design, freedom from being tied to a particular messaging library implementation, and eliminating unnecesssary overhead that affects communications latency.

This is a Java implementation of the XMIT protocol by Pantor Engineering AB (http://www.pantor.com). The XMIT specification can be found at http://blinkprotocol.org.

Build

In order to build xmit you must first make sure gradle can find a jblink.jar. A straightforward way is to place a copy of jblink.jar in the top-level xmit directory. Then you can build xmit by running gradle like this:

gradle build

Example

A sample server and client is available in the sample directory. You can build them by running gradle like this:

gradle build sampleJar

The following command line shows how to start the sample server on port 4711:

java -cp jblink.jar:build/libs/xmit.jar:build/libs/jxmit-sample.jar com.pantor.test.TestServer src/sample/pingpong.blink xmit.blink 4711

And this will start the client:

java -cp jblink.jar:build/libs/xmit.jar:build/libs/jxmit-sample.jar com.pantor.test.TestClient src/sample/pingpong.blink xmit.blink localhost:4711
